There is no doubt that there is a need to dramatically reduce consumption of fossil fuels. The aim of ETH Zurich's
new energy concept is to radically reduce the specific energy density in the area and thus also the CO2 emissions .
In doing so, the energy flows in the individual buildings will
be connected to efficient heat-recovery systems, for instance (technical and structural reduction scale).
With its dynamic underground storage system, ETH Zurich's campus Hönggerberg, will minimise consumption
of fossil-generated energy. Hönggerberg should become
fossil-free for heating by 2025. The underground storage
fields will be laid on an area of around ten football pitches,
and between 100 and 200 geothermal probes per field will
be arranged on a 5x5-metre grid at depths of 200 metres
into the ground. This depth offers the optimal combination
of energy storage and use for the system.
The underground storage systems will be subdivided into
geothermal probe groups in order to be able to respond to
different heating and cooling needs, especially in the transition periods. A ring-line network will connect the building
and the underground storage fields.
Individual buildings or building groups will be supplied
with energy via the centres, which are connected to the
ring-line network.
